WASHINGTON — A delayed supply run to the International Space Station is now set to launch April 14.

The private company SpaceX will be making its fourth trip to the space station from Cape Canaveral, Fla. The launch was postponed twice last month, the last time because of an electrical short on Air Force ground equipment.

NASA announced the new launch date on Friday.

The unmanned capsule, called Dragon, will bring up legs for the station’s humanoid robot, a grow lamp for vegetables in orbit and 5,000 pounds of supplies and experiments.

The California-based company will also test landing legs for the return of the first stage of the Falcon 9.
